1.1 Table "tree"
Table tree holds the structure of the ILIAS repository tree.

6 rows in set (0.00 sec)
The tree structure is represented using a "Nested Sets Tree With Gaps" and, for redundancy,
using an "Adjacency Map Tree".
The fields lft, rgt and depth hold the data elements needed for the Nested Sets Tree.
The field parent holds the data element needed for the Adjacency Map Tree.
The child field holds the reference id of an object in the repository. Table object_reference
can be used to find the associated object in table object_data.

 http://ffm.junetz.de/members/reeg/dev/DSP/node88.html
1.2 Table object_reference
Table object_reference links between table tree and table object_data.
The field ref_id is a foreign key to field child in table tree.
The field obj_id is a foreign key to field obj_id in table object_data.

1.3 Table object_data
Table object_data holds the base fields of all objects that ILIAS can work with.
This is not limited to objects in the repository. For example, table object_data also holds the
base fields for user objects.
Table object_data table is the superclass table of subclass tables in ILIAS with the suffix
_data. The prefix for the subclass table is stored in field type of table object_data.
For example, the base data for subclass table usr_data that is stored in table object_data has
the type 'usr'.
Warning: There are many tables with the suffix _data in the ILIAS database that are not
subclass tables of table object_data!

The field parent is a foreign key to field child in table tree. The child belongs to a role
folder object.
Note: The title of the role folder usually contains the object id, of its parent object. There are
some exceptions though. Notably the role folder in the administration view has the title
"Rollen".
2.2 Table "rbac_ua"
Table rbac_ua associates users with roles, that is, it holds the members of a role.
